EPA Finalizes New PM2.5 Rule

On February 7, 2024, the EPA finalized new annual NAAQS (National Ambient Air Quality Standards) that will reduce fine particulate matter (PM_2.5), sometimes known as “soot”, from 12 mcg/m³ to 9 mcg/m³. This marks the first time in a decade that the PM_2.5 rule has been revised and follows a June 2021 announcement by the EPA that the 2012 standards of 12 mcg/m³ appeared to be inadequate to protect public health and welfare.
